Impilo Olo luvo lucekeceke lulandelwa kwiindawo ezithile zobuchopho.Ngo-1999, ibhinqa elineminyaka engama-42 ubudala lahamba laya kwagqirha ngento awayeyichaza njengengxolo evelayo ezindlebeni zakhe zombini. Ingxolo yayikhwaza kakhulu yayiqale ukuyigcina ebusuku. Eli bhinqa lafunyaniswa ukuba liphethwe yiPalal Tremor, ukungahambi kakuhle kwezinye izihlunu ngasemva komqala, apho zingena khona kwaye zibangela isandi sokucofa.
Wanikwa iziyobisi eziphumlayo njenge diazepam, kodwa azisebenzi. Ngo-2004, esafuna unyango olusebenzayo, lo mfazi wabona ugqirha wemithambo owamnika i-5-HTP, i-amino acid eyenzeka ngokwendalo echaphazela inkqubo ye-nervous system. Yenza ukuphuma kwayo kwahamba, kodwa kwazisa iziphumo ebezingalindelekanga.
Waziva ukuba uphile ezi nje amaxesha afanayo, oku nje kwangolo suku lunye ngaphambili, uZeman uyachaza kwincwadi yakhe, Umzobo weBongo . Wayebanjiwe ngendlela engaqondakaliyo ekusebenzeni okuphindayo, inqaku lenqaku: imini yonke wayenengqondo yokwazi ngokuchanekileyo into eza kwenzeka ngokulandelayo.
Emva kweentsuku ezininzi esondele kuye, u-Shona wafumana uncedo kwezonyango, emva kokuba ethunyelwe kwisibhedlele sabagula ngengqondo. Wayeqale nokuba neemvakalelo ezikhethekileyo zomzimba, njengokutswina kwicala lasekhohlo lobuso bakhe, imvakalelo yokudada emoyeni ejonge ezantsi emzimbeni wakhe, kunye nemvakalelo yokunyanzelwa ukuba enze izinto.
Xa wayevavanywa, bafumanisa ukuba wayenokuxhuzula esemncinci. Nge-EEG baqaphela isenzo esingaqhelekanga kwicala lasekunene lengqondo yakhe kwaye bamfumanisa ukuba unesifo sokuxhuzula, okanye unesathuthwane ngaphandle kokuxhuzula. Emva kokunyangwa isifo sokuxhuzula, i-déjà vu yemka. UShona wayevuya kakhulu kukufumanisa ukuba umhlaba ubuyiselwe kwimeko yakhe yesiqhelo, ebangela ukuba abantu bangalindelanga, utshilo uZeman.
Xa wachacha kwi-déjà vu yakhe, nangona kunjalo, wayengasenakububona ubuso, imeko ebizwa ngokuba yi-prosopagnosia. UZeman uthi bafumene ukungaqheleki kwemithambo kwinxalenye yengqondo apho kwenzeka khona ukubonwa kobuso. Ukungaqhelekanga kwasekuqaleni kwakubonakalisiwe njenge-déjà vu ngaphambi kokuvela njengeprosopagnosia. Xa uZeman wadibana naye ngo-2000, wayengababoni abantu abadumileyo kumabonwakude kwaye izalamane zakhe kwakufuneka zizazise ngamagama ngalo lonke ixesha zisiza kumbona.
